In this work we describe a knowledgebase for the human ALU. The ontology is linked to SO and GO and is devoted to address the genomic context of the Aluome. For each ALU element, the closest gene and transcript are stored, as well their functional annotation according to GO, the state of the surrounding chromatin and the transcription factors binding sites inside the ALU. Semantic rules have been used to aid efficient data storage, querying and integration. The ALU ontology has been subjected to reasoners like Pellet and it is being transferred to a Semantic MediaWiki.
